A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
A custom structure in C++ (and various other languages) which can contain member data and functions. An instance of a class is called an object.
For questions about communication or data transfer between Arduino and Android devices. General Android questions can be asked on Android.SE.
Passive electronic component which reduces current flow in a circuit, dissipating power as heat.
For question related to environment with networks.
In-system programming (ISP) refers to the ability of chips to be programmed while installed in the system.
used to convert a serial string of bits into parallel data, or vice-versa.
